Conditions
Osteoarthritis, Knee
Pain

Drug: 5% ASKC200
Drug: 1% ASKC200
Registration Number
NCT06614608
Lead Sponsor
Jiangsu Aosaikang Pharmaceutical Co., Ltd.
Brief Summary

This is a multi-center, randomized, double-blind clinical trial to evaluate the safety, tolerability, pharmacokinetics, and efficacy of ASKC200 in subjects with OA of the knees and determine the phase II recommended dose. Assigned doses will be applied for 60 minutes on each of four consecutive days.

Detailed Description

Subjects will be randomized to one of the two Arms in this study: 5% ASKC200 or 1% ASKC200. All subjects will receive 4 consecutive days of treatment and will then be followed up until the Day 34 visit.

The NRS score of weekly average of average daily pain intensity (WAADPI) of the study knee should ≥ 5 and the NRS score of WAADPI of the contralateral knee should \< 4 at screening.

Data will be collected from Day 1 through Day 5 and then again on Days 19 and 34 for efficacy, tolerability, and safety measures.

Primary Outcome Measures
NameTimeMethod
Safety:Incidence of adverse events(AEs)34 days

All adverse medical events occurring after the subject receives the investigational drug, which may be manifested as symptoms, signs, diseases, or abnormalities in laboratory tests, but may not necessarily have a causal relationship with the investigational drug.

Secondary Outcome Measures
NameTimeMethod
Efficacy:Change in the NRS score of weekly average of average daily pain intensity(WAADPI) From BaselineDay 19, Day 34

The average amount of pain as reported by the subject using a 0 - 10 numerical rating scale (NRS). Higher scores indicate more pain.

Efficacy:Remission ratio of study knee according to NRS scoreDay 19, Day 34

The average amount of pain as reported by the subject using a 0 - 10 numerical rating scale (NRS). Higher scores indicate more pain.

Efficacy:Change in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain Score From BaselineDay 19, Day 34

The WOMAC Index is a questionnaire used to assess health status and health outcomes in KOA. The questionnaire contains 24 questions(0-10) on pain, stiffness and physiology, will ask participants to complete the WOMAC questionnaire considering their symptoms in the past 48 hours.Higher scores indicate more pain.

Efficacy:Change in patients clinical general impression (PCGI-C)Day 19, Day 34

The change in patients clinical general impression as reported by the subject using a 0 - 7 scale (PCGI-C).Higher scores indicate worse state of pain.

Efficacy:The use of acetaminophen34 days

Subjects will record their administration of acetaminophen . The number of days the subjects use acetaminophen and the proportion of subjects who use acetaminophen will be counted.
